@Stebalien incorporating 12c9510 into go-ipfs causes test failure in github.com/ipfs/go-ipfs/core/coreapi/test. I isolated it to a race condition caused by github.com/ipfs/[email protected], and found a portentous comment by @vyzo. This repo seemed like the appropriate place to report, as updating this dependency in IPFS will trigger the condition. I found this while rebasing and testing things on IPFS.
